<br />. rES 05 'SlO 17: 19 <br /> <br />_. ~ <br /> <br />I. Bttects ot Daa Operations <br /> <br />A. Effacts ot the Maqnitu~e of Daily Discharge Fluctuations, <br />Minimum Dis~hATges. and Rate of Chanae tRamping) or Fluctuating <br />Discharljles <br /> <br />1. Question: How significant are discharge fluctuations, <br />minimum discharges, and ramping in the degradation or aggradation <br />of beaches? <br /> <br />2. Question: Do discharge fluctuations, differences 1n <br />.minimum discharges, or different rates of change in daily <br />discharges (ramping rates) interact with other uses and <br />components of the Canyon to affect rates of sediment degradation? <br /> <br />3. QUestion: How do discharge fluctuations, minimum <br />discharges and rates of change of fluctuating diSCharges <br />influence the transport of sediment through the canyon? <br /> <br />4. Question: How do discharge fluctuations, minimum <br />discharges and rates of change of fluotuating discharges affect <br />trout? <br /> <br />5. Question: How do diSCharge fluctuations, minimum <br />discharges and rates of change of fluctuating diSCharges affect <br />foraginq success of wintering bald eaqles? <br /> <br />6. Question: How do discharge fluctuations and rates of <br />change in fluctuating discharge. affect other fish, especially <br />native fish species? Do the USFWS Conservation Measures <br />adequately address this question? <br /> <br />7. Question: Hew are water quality (nutrients and other <br />characteristics) and stream productivity (algae and <br />invertebrates) affected by discharge fluctuations, and the rate <br />of cbanqe in fluctuatinq discharges. <br /> <br />8. Question: How are recreational values influenced by <br />characteristics of discharge from Glen canyon Dam, such as <br />discharge fluctuations, minimum discharges and rates of change of <br />fluctuatinq discharqes. <br /> <br />9. Question: Are there sufficient camping beaches, in <br />location, numbers, and surface area, during high di~charge <br />periods (1.e., 31,500 cfs or possiblY 33,200 cfs) to satisfy the <br />needs of the recreational rafting community based on the NPS <br />acceptable carrying capacity of the Grand Canyon system? <br /> <br />10. Question: Do dam operations (e.g., magnitUde of stage, <br />magnitUde ot fluctuations and/or ramping rate) affect the <br />stability of cultural re.ource sites along the COlorado River in <br />Grand canyon? <br /> <br />2 <br />
